BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to managing network communications, and more particularly to a system and method for forwarding a file.

2. Description of the Related Art

Computing systems are commonly used in a network environment to share resources on the network. By way of example, a user on a client computing system may send a file to a destination at another computing system. For example, a facsimile communication may be sent from a client computing system to a server computing system.

In conventional systems, a facsimile communication may be forwarded from a recipient to a destination upon receipt of the facsimile communication.

BRIEF SUMMARY OF THE INVENTION

Some embodiments of the invention include, after receiving at least a portion of a file at a computing system, obtaining information about the file at a first time. First information is stored in a data structure, the first information comprising information that identifies the file and the information about the file at the first time, wherein, in the data structure, the information about the file at the first time is associated with the information that identifies the file. Then, information about the file at a second time after the first time is obtained. Second information is stored in a memory of the computing system, the second information comprising information that identifies the file and the information about the file at the second time. It is determined whether the second information matches the first information. In response to determining that the second information matches the first information, the file is sent from the computing system to a predetermined destination.

The network 108 may include one or more networks.

FIG. 2 is described with reference to the example network environment 100 of FIG. 1. FIG. 2 illustrates an example flow of operations at the server computing system 103.

In step S201, the server computing system 103 obtains information about a file at a first time. In some embodiments, the server computing system 103 receives this information receiving at least a portion of a file at the server computing system 103. The application 104 executing on the server computing system 103 may be periodically checking a folder at a storage location on the server computing system 103. For example, the application 104 may run a program on a loop; such that the application 104 takes a snap shot of the contents of a monitored folder on the server computing system 103 periodically. Accordingly, at a first time, the application 104 on the server computing system 103 may take a snap shot of all of the files in the folder at a first time and thereby obtain information about the each file at the first time. In some embodiments, one or more files in the folder comprise respective facsimile communications. The files may be all or a portion of a file. For example, each file may be all or a portion of a facsimile communication.

In some embodiments, the information about the file at the first time is information indicating a time the file was last written to as of the first time and information indicating a size of the file at the first time. For example, the information indicating a time the file was last written to as of the first time may be LastWriteTime information for the file and it may indicate a time the file was last written to in the folder. Additionally or alternatively, in some embodiments, the information about the file at the first time may include information indicating a size of the file at the first time. For example, the information indicating the size of the file at the first time may be FileSize information. The information about the file at the first time may be in any suitable format.

In step S202, the server computing system 103 stores information in a data structure. The server computing system 103 may store first information in a data structure. The first information may be information that identifies the file and the information about the file at the first time that was obtained in step S201. In some embodiments, the information about the file at the first time is associated, in a data structure, with the information that identifies the file. For example, as illustrated in FIG. 3, information that identifies the file may be a file name such as “File 1” and the information that identifies the file may be associated with information that identifies the file such as LastWriteTime or FileSize information obtained in step S201.

In step S203, the server computing system 103 waits a predetermined amount of time. For example, the server computing system 103 may monitor a timer and the determine that a lapse of a predetermined amount of time since the first time has occurred. Upon determining the predetermined amount of time has lapsed, the process advances to step S204.

In step S204, the server computing system 103 obtains information about file(s) at a second time. In step S204, the server computing system 103 takes a snap shot of the same folder as in step S201 in order to obtain information about the contents of the folder at the second time. The operation performed in step S201 is repeated in step S204.

In step S205, the server computing system 103 stores second information in a memory of the server computing system 103, the second information comprising information that identifies the file and the information about the file at the second time. The second information may be stored in a cache memory of the server computing system 103.

The information about the file at the second time is information indicating a time the file was last written to as of the second time and information indicating a size of the file at the second time. For example, the information indicating a time the file was last written to as of the second time may be LastWriteTime information for the file and it may indicate a time the file was last written to in the folder. Additionally or alternatively, in some embodiments, the information about the file at the second time may include information indicating a size of the file at the second time. For example, the information indicating the size of the file at the first time may be FileSize information. The information about the file at the first time may be in any suitable format.

In step S206, the server computing system 103 compares the information stored in step S205 to the information stored in step S202. The information is compared for each file for which information was obtained during the snap shots.

In step S207, if it is determined that there was a match between the first information and the second information, then the server computing system identifies a predetermined destination in step S210 based on a configuration parameter indicating a destination for the server computing system 103 to forward the file. The file may be a facsimile communication. The configuration parameter may be information that identifies the predetermined destination.

In step S211, the server computing system 103 sends the file to the destination identified in step S210. At step S212, the server computing system deletes the file.

On the other hand, if the first information does not match the second information in step S207, then the process advances to step S208.

In step S208, the second information (i.e., the information in memory) replaces the information in the data structure. For example, in FIG. 4, a second data structure is shown. In the example of FIG. 4, the file named File 1 is no longer present because a match between data in memory and data in the data structure of FIG. 3 was identified. In other words, between the first time and the second time, there was no change between the values for File 1. However, for File 2, there was a change, so File 2's new information is now stored in the data structure in FIG. 4. Still further for File 3, at the second time File 3 was newly found in the folder during the snap shot. Thus, File 3 is now newly added to the data structure.

At step S209, the process repeats for each file in the data structure.

If all files have been checked, the process returns to step S203.
